Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a waterproof floor for large areas constructed inside a building.

One way to construct a waterproof floor is to place a single waterproof panel on the floor of a building. However, with this method, it is only possible to construct a waterproof floor with an area equivalent to one piece of waterproof pan, making it difficult to construct waterproof floors for multi-room toilets, kitchens, etc. that require a large area. Therefore, conventionally, a so-called wet construction method has been adopted in which a waterproofing agent made of asphalt or the like is applied to the floor surface of a building, and then finishing mortar or the like is poured onto the waterproof layer.

However, in the conventional so-called wet construction method, the waterproof floor construction work and the piping work cannot be carried out at the same time and must be carried out alternately, which has the disadvantage that the construction period becomes long.

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks, the present invention aims to provide a waterproof floor that can be constructed using a so-called dry construction method and has a large floor area.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments shown in the drawings. FIG. 1 is a longitudinal sectional side view with the middle omitted, showing an embodiment of a waterproof floor 1 according to the present invention. waterproof floor 1
is a joist frame group 4 formed by arranging a plurality of joist frames 3, 3... in a level-adjusted state on a floor surface 2a of a building 2, and the joist frame group 4.
The floor structure 6 is formed by watertightly joining the adjacent flanges of a plurality of water-impermeable unit panels 5, 5, . . . placed on the upper surface of the floor structure. The joist frame 3 includes joist materials 3a, 3a...
are connected and assembled in an appropriate shape such as a grid, and are placed on the floor surface 2a at a predetermined level by adjusting the level adjustment screws 3c, 3c, etc., which are provided in advance on the backing plates 3b, 3b, which are joined to the four corners. After placing, mortar etc.24
is fixed. The external dimensions of the joist frame 3 are of a size convenient for handling such as transportation (for example, 1000
mm×1500mm) is adopted. The water-impermeable unit panel 5 is formed by processing an FRP plate, a metal plate, or the like. The water-impermeable unit panels 5, 5 are joined together by connecting the corresponding joining flanges 5a, 5a with screws 7, 7, . is joined to. In addition, the floor structure 6
Attach screws 2 to the joist frame group 4 as necessary.
5, and the head of the screw 25 is sealed 8 in a watertight manner.

FIG. 2 is a partially cutaway plan view showing an embodiment of another aspect of the present invention, and FIG. 5 is an enlarged sectional view of the same main part. The joist frames 10, 10 are held together with clamping pressure.
The water-impermeable unit panels 12, 12 are connected to each other in a water-tight manner via the mounting plate 14. Adjacent joist frames 10 and 10 are joined together at an appropriate pitch (for example, 500mm ) are bolted and joined 15, 15, . . . . The joist frame group 11 configured in this way has a backing plate 1 of each joist frame 10, 10...
0b, 10b, . . . are fixed with anchor bolts 16, and if necessary, the vicinity of the backing plate 10b is fixed with mortar or the like 24. As shown in FIG. 5, the water-impermeable unit panel 12 includes a water-impermeable surface layer 12a made of an FRP plate, a metal plate, etc., and the surface layer 1
It consists of a reinforcing material 12b made of a wood wool cement board or the like placed on the back side of the reinforcing material 2a, and a filling layer 12c made of resin concrete or the like filled into the back side so as to cover the reinforcing material 12b. The water-impermeable unit panel 12 has bolt guide recesses 12d, 12d... recessed at an appropriate pitch (for example, 300 mm) near the upper edge on the joint surface side, and
A bolt insertion hole 12 opens between the inner surface of the recess 12d and the outer joint surface of the water-impermeable unit panel 12.
e, 12e... are bored. Water-impermeable unit panel 1 forming corners and sides of floor structure 11
2 has an upright wall 12f erected on the upper edge of the non-joining surface side. A piece of wood 26 is fitted into the back side of the upright wall 12f as necessary.
Wall panel installed on the top of 2F (not shown)
The structure is such that the runner 17 can be securely screwed to support the runner 17. On the upper surface of the water-impermeable unit panel 12, tiles 18, 18, . The water-impermeable unit panels 12, 12
The connection is made between the adjacent and opposing outer joint surfaces of the water-impermeable unit panels 12, 12 placed on the joist frame group 4, and the attachment plate 14 through packings 19, 19 made of rubber plates or the like. The upper halves of the two are held together, and the bolts 20 inserted into the bolt insertion holes 12e and 12e are tightened to make the two watertight. After joining with the bolts 20, the joint upper surface groove 22 is filled with a sealant 8 made of a silicone sealant or the like as necessary, and the recesses 12d, 12d are filled with a filler 21 made of a resin filler or the like. . Finally, move the tile 1 to the missing tile area as shown by the two-dot chain line in the figure.
8, 18, . . . and joints 23 are attached to form the floor structure 13.

As described above, the waterproof floor according to the present invention has the following excellent effects.

Since it is composed of multiple joist frames and multiple impermeable unit panels, it is possible to construct a waterproof floor over a large area.

Since it can be constructed using the so-called dry construction method, it is possible to carry out the waterproof floor construction work and piping work in parallel, and the construction period can be significantly shortened compared to the conventional wet construction method.

Since it is possible to use a joist frame and a water-impermeable unit panel manufactured in advance according to the specifications in a factory, it is possible to provide a waterproof floor with high precision and at low cost.
